4. have you updated the change log?
5. do you think that you can understand your changes after 6 month?

I read through the changelog and cannot find any entry describing the addition of handlebars as an engine option - would you also like me to add that to the changelog?

@CLiu13 We do not intend to include handlebars in the main repo. Infact we will be moving it to a separate repo. So it can't be a additional feature to main repo.

@CLiu13 , the change log looks OK. please do this:

1. update it in .moban.cd/changelog.yml
2. then call make update, which auto generates changelog.rst

Otherwise, next make update will overwrite your change log.

I know it is new piece of information. Please feel free to update docs.

[chfw]

please update it in changelog.yml instead.

[CLiu13]

Thanks for the info on the correct way to update the changelog. Running make update resulted in some additional changes in other files, which I have included for now - but let me know if you would like me to exclude them.

EDIT: One of those changes resulted in failing travis tests - as a result, I will exclude that change.

good to go
